CSO 966 aluminium 51T rear pulley
CSO Racing have released this rear axle pulley for the Serpent 966 and 960. Made from 7075 T6 aluminium, this 51T pulley has been lightened through strategically positioned holes and thanks to additional holes along the side walls of the teeth it will help prevent the build of dirt which can damage the rear belt.
